LM-S on the Hermann monument in Detmold, Germany

This application example shows how the lightning detection system is used on the Hermann monument in Detmold, Germany. The copper statue stands upon a sand-lime brick base. Three grounding cables are connected to the plinth of the statue. This means that if the structure, which is over 53 meters tall in total, is hit by a lightning strike, the lightning surge currents are diverted to ground. The sensors are mounted on these down conductors. The evaluation unit is installed in a control cabinet inside the base.

In the case of this application, early detection of potential damage to the system is not the key objective. However, due to the exposed location and the height of the structure, significant lightning strikes should be expected. The detection of these strikes is used to statistically evaluate lightning strikes and their strength. Such applications are of particular interest for lightning research.
